The music in a video should complement the images so the suitability of the music would depend on the video subject. I can't think of any company marketing video that would suite these pieces but there could be some other sort of video they would fit. Yes, they are a bit dark. Most companies would want to create a positive image so the music would need to have a positive feel to it.

Dark music -> dark product. I could imagine it as background music for e.g. a tattoo studio or an underground club. The last one is fine for marketing considering the mood it creates but lacks some highlights.
